Woman Killed After Being Struck on Highway 4 Near Contra Loma Boulevard in Antioch

A 20-year-old woman died early Sunday after she was struck by two vehicles on eastbound Highway 4 just east of Contra Loma Boulevard in Antioch, according to the California Highway Patrol.

CHP officers responded at about 2:31 a.m. on October 4. According to the CHP's preliminary investigation, the woman had been riding as a passenger in a vehicle on eastbound Highway 4 when an item was lost onto the freeway. The vehicle pulled over in the center median, and the woman got out and walked into the traffic lanes to retrieve the item. She was struck by two vehicles and was pronounced dead at the scene.

Both drivers stopped and cooperated with investigators, the CHP said. Officers said they do not suspect alcohol or drug impairment as a factor at this time. All eastbound lanes near Contra Loma Boulevard were closed from about 2:49 a.m. to 5:27 a.m., and Antioch police advised that the eastbound on-ramp at Contra Loma Boulevard would stay closed for an extended period.

The woman's name had not been released as of October 5. The crash remains under investigation.

Why Freeway Pedestrian Crashes Need a Careful Investigation

Pedestrian crashes on a freeway often happen at night, at high speed, and with little time for drivers to react. Investigators may look at lighting, visibility, vehicle speeds, lane positions, where the stopped vehicle was parked, and the sequence of impacts when more than one vehicle is involved. Highway 4 through Antioch is also a busy freight route, and our Antioch truck accident lawyer page explains how claims differ when a commercial vehicle is involved.

Evidence such as Caltrans traffic camera footage, dashcam video, vehicle data, and witness statements can be lost quickly if it is not requested early. No conclusion about fault should be drawn from the limited information released so far.

Questions Families May Face After a Fatal Highway 4 Crash

After a death on the freeway, families often have questions about what happened and whether any insurance coverage may apply. The answers depend on facts the investigation is still developing, including the role of each vehicle involved.

California generally allows two years to bring a wrongful-death claim, though some cases involve shorter deadlines. Families should get case-specific guidance rather than relying on a general rule.
